BURGLAR-PROOF-SAFE DOOR.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed December 9, 1908. Serial No. 532,229.

T 0 all whom it may concern:

Be it known that I, LYMAN G. GLAZIER, a citizen of the United States,residing at Pomfret Center, in the county of \Vindham and State ofGonnecticut, have invented a certain new and useful Improvement inBurglar-Proof-Safe Doors, of which the following is a specification.

My invention relates to a new and useful improvement in burglar proofsafe doors, and has for its object to provide an exceedingly simple andeffective device of this character which may be readily opened by anyoneknowing the combination, but cannot be blown from place.

In accomplishing the above named objects, I employ a round door havingthreads upon its periphery, which mesh with threads formed in the dooropening in the front of the safe, and being round and threaded it isnecessary to remove said threads in some manner before the door can betaken from its place, unless the combination has first been manipulated.To remove said threads it will be necessary to use a number of chargesfor blowing them away, or else use a charge suflicient to blow the safein half, which would of course destroy the contents, thereby renderingthem worthless.

A still further object of the invention is to provide a carriage forswinging the door open or closed, which will be entirely hidden when thedoor is closed.

A still further object is to provide a door holding member hinged to thecarriage so that the door will swing into different positions when open.k

With these ends in view, this invent-ion consists in the details ofconstruction and combination of elements, hereinafter set forth and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which Figure 1 is afront elevation of a safe embodying my improvement showing the doorclosed. Fig. 2, a similar view, the door being open. Fig. 3, a sectionat the line oc-w of Fig. 1 looking in the direction of the arrow, aportion of the safe being broken away, and Fig. 4, a plan view of aportion of the safe showing the door swung back to its full extent andshowing in dotted lines one of the other positions which it may take.

In carrying out my invention as here embodied, A represents the body ofthe safe, having a circular door opening B formed in the front wallthereof, said opening having threads C formed in its side walls. Back ofthe door opening is formed another opening D, which passes to theinterior of the safe, and of any desirable shape to form the ribs E, andin one of these ribs is formed the indentation F for the reception ofone end of the carriage G, which is hinged at this point to the safebody. The free end of this carriage has a semi-circular opening H formedtherein, thus producing arms I, to which is hinged the door carryingmember J, by the hinges K.

The door carrying member has a circular opening L formed therein andwhich is provided with threads M in its inner walls, with which mesh thethreads N formed on the periphery of the circular projection O, which ispreferably formed on the inner face of the circular door P, whoseperiphery is provided with threads Q.

The door carrying member J has a lip R which registers with the pocket Sin one of the ribs E when the door is closed, thus relieving a portionof the strain upon the carriage and also stopping said carriage when thedoor is in position for its threads to mesh with the threads in the dooropening.

On the outer face of the door is placed a wrench hold 'I, on which maybe placed a suitable crank or handle for turning the door to either openor close it.

In practice the combination will be similar to that used in other safes,and when manipulated to unlock the bolts, said bolts may be turned backand a crank placed upon the wrench hold T and the door threaded from thedoor opening. WVhile backing off the door, the projection 0 willpartially back out of the door carrying member J but will not threadentirely out. This will allow the door to be swung to any position thecarriage and door carrying member will take.

as these may be varied within the limits of the appended claim withoutdeparting from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is

In combination, a safe having a circular threaded door openingandanother opening of smaller size, thereby forming ribs, a number of whichare provided with apertures, a carriage hinged to one of said ribs andresting in the aperture formed therein, said carriage having asemi-circular opening formed in its free end, thus producing arms, adoor carrying member provided with a threaded circular opening andhaving a lip which engages the aperture in one of the other ribs,

said door carrying member being hinged to the arms of the carriage, acircular door having threads formed upon its periphery, a threadedprojection formed on the inner surface of said door, engaging thecircular opening in the door carrying member, and a wrench hold mountedon the outer surface of said door, for the purpose set forth.

In testimony whereof, I have hereunto aflixed my signature in thepresence of two subscribing witnesses.

LYMAN G. GLAZIER.
